<p>
      Boost.Algorithm is a collection of general purpose algorithms. While Boost
      contains many libraries of data structures, there is no single library for
      general purpose algorithms. Even though the algorithms are generally useful,
      many tend to be thought of as "too small" for Boost.
    </p>
<p>
      An implementation of Boyer-Moore searching, for example, might take a developer
      a week or so to implement, including test cases and documentation. However,
      scheduling a review to include that code into Boost might take several months,
      and run into resistance because "it is too small". Nevertheless,
      a library of tested, reviewed, documented algorithms can make the developer's
      life much easier, and that is the purpose of this library.
    </p>

    </h4>
<p>
      I will be soliciting submissions from other developers, as well as looking
      through the literature for existing algorithms to include. The Adobe Source
      Library, for example, contains many useful algorithms that already have documentation
      and test cases. Knuth's <span class="underline">The Art of Computer Programming</span>
      is chock-full of algorithm descriptions, too.
    </p>
<p>
      My goal is to run regular algorithm reviews, similar to the Boost library review
      process, but with smaller chunks of code.

<p>
      Boost.Algorithm uses Boost.Range, Boost.Assert, Boost.Array, Boost.TypeTraits,
      and Boost.StaticAssert.

<p>
      Thanks to all the people who have reviewed this library and made suggestions
      for improvements. Steven Watanabe and Sean Parent, in particular, have provided
      a great deal of help.
